- This article is about the school itself. You may be looking for its true form, the Nirvana.
The school was a source of pride for the town, as no elementary school had stood within Tenjin's borders at all prior to its construction in 1952. Primary school students had previously been commuting to neighboring towns for class, and consequently Heavenly Host Elementary School became the most desirable school to go into in that area.
It was finally torn down on November 18th, 1975 following a string of serial kidnappings and murders. Thanks to the power of Sachiko Shinozaki, however, it continues to exist on the spiritual plane as a nexus of multiple dimensions inhabited by vengeful spirits from which it is nearly impossible to escape known as the Nirvana. The situation became even worse after Naho Saenoki wrote about the charm in her blog, allowing for large amounts of students to be trapped in the school.
